A Canadian woman who flew to Syria to join the fight against ISIS has reportedly been captured.

Gill Rosenberg, 31, left North America to join the ranks of the Kurdish Peshmerga fighting force, which has elite all-female units.

Rosenberg, a joint citizen of Israel who served in the Israeli Defense Force, went to fight against the so-called Islamic State earlier this month, while they were locked in combat over Kobane, a town on the Turkey-Syria border.

She had earlier posted on social media explaining her decision to go and fight, declaring she sympathized with the Kurds, whose territory has come under heavy assault.

Her position in the Israeli military is thought to have been a non-combat role.

But, according to the Times of London, militant sources have written online that Rosenberg was captured, along with several other female Peshmerga fighters.

She was reportedly taken hostage on Friday, when ISIS members hit Kobane with several suicide car bombs.

A spokesman for the Canadian foreign ministry said the government is 'aware of reports that a Canadian citizen was kidnapped in Syria.'

'Canada is pursuing all appropriate channels to seek further information and officials are in close contact with local authorities.'

According U.S.-based jihadist monitoring group SITE, militants were messaging one another online about whether it would be better to execute Rosenberg or attempt to trade her for prisoners held by the West.

However, some sources have cast doubt on the idea that she is in the area at all.

IS jihadists began advancing on Kobane on September 16, hoping to quickly seize the small town and secure its grip on a large stretch of the Syrian-Turkish border, following advances it made in Iraq.

At one point, it looked set to overrun the town, but Kurdish Syrian fighters, backed by coalition air strikes and an influx of Iraqi Kurdish Peshmerga forces, have held back the group.

The ambush came as news emerged that Lebanon detained in the nearby town of Arsal a wife and young son of Abu Bakr al-Baghdadi, the head of the jihadist Islamic State (IS) group that has seized large parts of Syria and Iraq.

Whether they're directly cooperating or just "deconflicting," the US air force is operating alongside the Syrian and the Iranian air forces over Iraq and Syria.

On Monday, an unnamed US defense official told the Huffington Post that the US was aware that the Iranian Air Force was carrying out air strikes against ISIS targets in eastern Iraq.

"We are aware of that. I wouldn't say we're necessarily concerned with it — we kind of have our eyes on it," the official told the Huffington Post. The official noted that the Iranian strikes occurred close to the Iran-Iraq border, away from where the US coalition has normally carried out airstrikes.

According to David Cenciotti, a military aviation expert and editor of The Aviationist, it's unlikely that Iranian aircraft would fly inside of Iraq without at least informing the US-led coalition of their presence and intentions.

"Although it is theoretically possible for Iranian planes to fly inside Iraq without any coordination with other air forces operating in the same airspace, it would be suicidal," Cenciotti told Business Insider. "For proper deconfliction of tactical assets, prior coordination and air space management and control are required. There are several aircraft performing Airspace Control and Airborne Early Warning over Syria and Iraq: no plane could fly undetected in the area."

In Syria the US and the government of President Bashar al-Assad have even reached an uncomfortable tacit alliance. Within the past week both Damascus and Washington have carried out independent air strikes against the Syrian city of Raqqa, ISIS's de facto capital.

“What do you expect any sane person to think here? One day American airplanes and the next Bashar’s, how do they not crash or shoot each other? It is simple, they call each other and say today is my turn to kill the people of Raqqa, please don’t bother me, it will be yours tomorrow,” a Syrian resident of Raqqa told Syrian citizen journalist Edward Dark.

The confluence of US and Syrian objectives towards ISIS, and the gradual US acceptance that Assad may have to become a partner in the war against the jihadist militants, has led to no shortage of future difficult or even compromising scenarios for the White House.

“This is all quite awkward for Washington,” Imad Salamey, a professor of international relations at the Lebanese American University in Beirut, told The Washington Post. “It definitely seems like the Syrian regime has craftily manipulated the coalition agenda to help its own agenda.”

The Iranian airstrikes seemed to be in support of a joint Iraqi and Kurdish Peshmerga military operation aimed at pushing ISIS out of Sa’adiya and Jawlala, towns along the Iranian border.

US airstrikes in Iraq have tended to be focused around key infrastructure like the Mosul Dam and the Yazidi enclave of Sinjar, although some strikes have been aimed at hitting ISIS militants closer to the Iranian border south of Kirkuk.

European Union governments agreed on Friday to ban the export of jet fuel to Syria from Sunday, saying it was being used by the Syrian air force for indiscriminate attacks against civilians.

The ban also covers finance and insurance related to jet fuel exports to Syria.

However, fuel and additives exclusively used by non-Syrian civilian aircraft landing in Syria will be exempt, so these planes can continue their onward flights.

Europe is heavily dependent on jet fuel imports from the Middle East and it was not immediately clear how much fuel the 28-nation bloc actually exported to Syria.

The United Nations says at least 3.2 million people have fled Syria and 200,000 have been killed in the more than three-year-old civil war, which broke out after protests against President Bashar al-Assad's government.

EU ministers agreed in principle in October to ban jet fuel sales to Syria, but the details have only now been worked out.

"A significant number of innocent civilians ... have died because the Assad regime's air force has deliberately dropped weapons, including barrel bombs," Britain's Middle East Minister Tobias Ellwood said in a statement.

"This measure will ensure that no EU people or companies will be involved in jet fuel going to Syria. I urge all nations to ban jet fuel going to the Assad regime," he said.

Legal texts with a detailed list of fuel types and additives covered by the ban will be published in the EU's Official Journal on Saturday.
